Watch TCM feature - TWC TV and Apps

TCM has a feature called Watch TCM which allows viewers to either watch the channel live or pick from a list of movies that have aired within the last week. This has been going on for a few years but Time Warner Cable wasn't part of it.

So, finally with Spectrum I figured it would be a cinch since Charter Spectrum is listed as being among the partners (along with a buch of other cable companies).

But I keep getting an error message that either my user name or password are wrong, but they are the same ones that i use to get here, so what gives?

Thankis in advance.

This question is about "Watch TCM feature", with Time Warner Cable TV and apps.
